Unity Exception: No such proxy method: onPaidEvent

[Vasily Che]

Hi all.

I'm embedding a native google admob in my unity project as described here.

Almost everything worked, however I have one question: when I test the android build, each time after native ads loading and calling the OnImpressionTrackedEvent callback I see an exception in the console:

E/Unity: Exception: No such proxy method: _lrzYIkvPC4Ct86Sgf1d6FlyaJ3M._eXQBkxLYQ0eJrSK9oYuIIkse1ON.onPaidEvent

Please tell me what can be done to get rid of this exception?

Log is here

The version of the library is not explicitly specified, but in GoogleMobileAdsDependencies.xml I see the following

<androidPackage spec="com.google.android.gms:play-services-ads:19.5.0">
<androidPackage spec="com.google.code.gson:gson:2.8.5">

[Vasily Che]

Some clarifications:

1. Sample app source code could be found here, compiled apk is here

2. Steps to reproduce:

 - Install and run the attached file AdMobTest.apk

 - Click "Init ads" button

 - Wait until "Request ads" button becomes active

 - Press "Request ads" button.

Expected result: Ad loaded and registered successfully, no exceptions
Actual result: Ad assets registration throws the following exception: No such proxy method: _lrzYIkvPC4Ct86Sgf1d6FlyaJ3M._eXQBkxLYQ0eJrSK9oYuIIkse1ON.onPaidEvent

Please see attached AdMobTest_log_1.txt

3. Unity Version

Reproducible on: Unity 2020.3.18, Unity 2020.3.30

4. SDK version:

SDK version is not explicitly specified, unity package is called GoogleMobileAds-native.unitypackage, and does not contain any version declaration

In GoogleMobileAdsDependencies.xml I see the following versions: com.google.android.gms:play-services-ads:19.5.0, com.google.code.gson:gson:2.8.5

Hi Vasily,

Thank you for providing the requested information.

Can you confirm if you implemented both unity plugin and native plugin in your application where you encountered this error? In addition to that, can also you confirm if you've tried to use the new unity version that supports and tested on the new version(Google Play services 20.6.0) of the AdMob SDK for android?

Hi Princess Pamela

>Can you confirm if you implemented both unity plugin and native plugin in your application where you encountered this error?

Yes.

I imported unity plugin (I tried both GoogleMobileAds-v6.1.2.unitypackage and GoogleMobileAds-v7.0.0.unitypackage)  into the project then I imported the native plugin (GoogleMobileAds-native.unitypackage)

(please note that GoogleMobileAds-native overwrites the following libraries during the import process: GoogleMobileAds.dll, GoogleMobileAds.Core.dll and GoogleMobileAds.Common.dll)

After that I can reproduce described behavior: on native ad asset registration I can see the following exception

Unity: Exception: No such proxy method: _lrzYIkvPC4Ct86Sgf1d6FlyaJ3M._eXQBkxLYQ0eJrSK9oYuIIkse1ON.onPaidEvent(System.Int32,System.Int64,System.String)

>In addition to that, can also you confirm if you've tried to use the new unity version that supports and tested on the new version(Google Play services 20.6.0) of the AdMob SDK for android?

GoogleMobileAds-native overwrites GoogleMobileAdsDependencies.xml and replaces play-services-ads:20.6.0 with play-services-ads:19.5.0.

Please see attached GoogleMobileAds-native import screenshot

Hi Vasily,

Thank you for your response.

Since you mentioned that you're using both unity plugin and native plugin. This might be the reason for these errors as GoogleMobileAds-native.unitypackage is not compatible with GoogleMobileAds-v6.x.x.unitypackage. Then for the new version of unity plugin to be compatible with the native plugin, we will be releasing a separate Native ads plugin that will have a dependency on this main plugin. 

[Vasily Che]

Hi, Princess Pamela

If I understood you correctly, the problem I wrote about is that I am using two incompatible packages (native and unity).

I tried to check this assumption by deleting all previously imported packages and partner network mediations, and re-importing only GoogleMobileAds-native

(at this point I must apologize for my own stupidity: after re-importing I noticed the file CHANGELOG.MD which contains the SDK version you asked about = "Version 5.4.0.90")

Then I re-build apk and the bug is still reproducible.

Thus, the problem is not related to package compatibility.

 suppose the problem could be caused by one of two things:

1. A bug inside GoogleMobileAds-native.unitypackage - this is unlikely, because in that case there would be more posts about this problem on the Internet

2. Icorrect usage of GoogleMobileAds-native on my side. However, I can't find what could be wrong, as for the most part my code copies what was shown in the example here https://developers.google.com/admob/unity/native-advanced-unified

Hello Mark, hello Princess Pamela

Thanks you for your response.

I've uploaded updated sample project (SourceCode.zip, AdMobTest.apk and AdMobTestLog_2.txt) to the google form provided by Mark

Steps to reproduce are the same:

 1. Install and run the attached file AdMobTest.apk

 2. Click "Init ads" button

 3. Wait until "Request ads" button becomes active

 4. Press "Request ads" button.

 5. Wait until ad is loaded and applied

Please note that according to my investigations exception is thrown when I try to register ad gameobjects, please see "NativeAdView" class "RegisterObjects(UnifiedNativeAd nativeAd)" method

PS

I apologize if I'm sending this message to the wrong thread, or sending it twice. I see the message from Mark in the mail, but I don't see it here. Please advice, is it enough for me to reply to the mail message through my mail browser, or do I have to write a reply here? Right now I'm replying there and here, just in case

Hello Mark, hello Princess Pamela

Sorry to interrupt.

I just wanted to check if everything is OK with the sample project I sent in on March 23 and the steps to reproduce the bug. Maybe you need any additional info from me?

Hi Vasily,

 

The Google Mobile Ads Native plugin 7.0.0 requires the Google Mobile Ads plugin version 7.0.0 to work. [Can you please upgrade the plugin](https://github.com/googleads/googleads-mobile-unity/releases/tag/v7.0.0) and try again?

Thanks,

Nick

Hello Nick!

Bug is reproducible with the latest version of Google Mobile Ads Native and Google Mobile Ads plugin (btw, native plugin integration documentation became outdated after the plugin update).

I did some research and found that the bug is reproducible when I add ARM64 to target architectures list.

It is not reproducible when target architecture == ARMv7.

Hope it helps

WBR,

Vasily

Hi Vasily,

I hope you're doing well.

I just want to circle back on this. The team mentioned that this has been fixed. Feel free to come back to us if you still encounter any issues regarding this.

[Vasily Che]

Hello Princess Pamela

Im doing well, thanks. Hope you’re doing well, too

I've checked the fixing with the latest Google Mobile Ads Native and Google Mobile Ads plugin and have to say that the bug is not fixed, I'm still receiving "No such proxy method" exception

The only difference is that obfuscated class/method names are changed: earlier it was

Exception: No such proxy method: _lrzYIkvPC4Ct86Sgf1d6FlyaJ3M._eXQBkxLYQ0eJrSK9oYuIIkse1ON.onPaidEvent

and now it is

Exception: No such proxy method: _zJZ3lrBcaj0LlWJ3jFnsJmJ4jKI._vq9Y5qtiHxlHVgL0XzyZXl9nbnF.onPaidEvent
